This vehicle isn't offered in the US, so I have very little technical info. Can you tell me if the belt is a serpentine belt or does the alternator have a separate belt?
If there is only one belt, it is routed correctly, and you have the correct belt, then the belt tensioner is most likely bad.
Check if the tensioner is moving correctly and it is strong.
Let me know.
